You can try DateAdd() function

I'd suggest you also look into the DateDiff() function, which is specifically designed to calculate the differences between dates and/or times.

We can't do the work for you, though. See the following standard warning...

Attempt the assignment/program yourself first and post questions regarding any difficulties you have or about a particular function of the code that you don't know how to achieve.

Try to use DTPicker control instead of using combobox.

Use DateDiff function for the difference in time.

I'll use Date different
my program works already to the 2 condition but but it will not work if the user will input first to the time

her is the format

hour = 2
start time = 05:00 AM
end time = ?


thank you...

I don't think I completely understand the latest question. But if you have a time and a number of hours to add to it, that's where the DateAdd() function would be used.
